查询词典 emission spectrum

Photoluminescence properties of ZnSe/silica gel-glasses were investigated by an advanced spectrum system. Excitated by laser of two different wavelength, the electron transition occurred in two different relaxation approaches. Interband radiation spectra and the surface defect radiation spectra of ZnSe nanoparticles were obtained. The correlation between the wavelength of eradiated light and the incident light verifies that the electronic-hole structures change with the size of the nanoparticle.
